본 발명은 이중 PTC 히터를 이용한 차량용 난방장치에 관한 것으로, 보다 구체적으로, 전기자동차의 공조장치에 포함된 전기 가열장치(이하, PTC 히터: Positive Temperature Coefficient)에 좌우독립기능을 적용함으로써 운전석과 조수석의 온도를 조절하고, 상하 측의 온도차를 발생하게 하여 열적쾌적성을 제공하기 위한 PTC 히터를 이용한 차량용 난방장치에 관한 것이다.
The present invention relates to a vehicle heating apparatus using a double PTC heater, more specifically, the driver's seat and the passenger seat by applying a left and right independent function to the electric heating device (hereinafter, PTC heater: positive temperature coefficient) included in the air conditioner of the electric vehicle The present invention relates to a heating device for a vehicle using a PTC heater for controlling the temperature of the temperature and generating a temperature difference between the upper and lower sides.

일반적으로 차량에는 그 차량의 실내 온도를 조절하기 위한 공조장치가 설치되어 있다.Generally, a vehicle is provided with an air conditioner for controlling the room temperature of the vehicle.

이러한 공조장치는 내연기관 엔진 차량의 경우 냉각수가 순환하는 배관에 열교환기를 설치하고 그 열교환기에 공기를 이동시키면서 차량 내부의 온도를 조절하고 있다.In the case of an internal combustion engine engine vehicle, the air conditioner installs a heat exchanger in a pipe through which cooling water is circulated, and controls the temperature inside the vehicle while moving air to the heat exchanger.

한편, 난방장치는 엔진의 폐열을 사용하고 있는바, 최근 개발되는 차량의 엔진의 효율이 높아짐에 따라 히터시스템의 열원으로 사용되는 엔진폐열의 부족으로 초기 난방에 문제가 있어, 별도 전기식 히터인 PTC 히터를 보조열원으로 사용하고 있다. On the other hand, the heating device uses the waste heat of the engine, and as the efficiency of the engine of the recently developed vehicle increases, there is a problem in the initial heating due to the lack of the waste heat of the engine used as a heat source of the heater system. The heater is used as an auxiliary heat source.

그러나, 전기자동차에서는 내연기관처럼 엔진의 폐열이 없으므로 별도의 열원을 확보하여야 한다.However, in the electric vehicle, since there is no waste heat of the engine like the internal combustion engine, a separate heat source must be secured.

상술한 바와 같이 난방 시 문제점을 해결하기 위하여 종래에는 PTC 히터 또는 히팅버너 시스템을 보조히터로 사용하는 기술이 개발되어 있다.As described above, in order to solve the heating problem, a technique of using a PTC heater or a heating burner system as an auxiliary heater has been developed.

또한, 최근에는 친환경 에너지에 대한 관심이 높아지면서 전기자동차에 대한 관련부품 개발이 급속히 진행되고 있는 상황이다.In addition, recently, as interest in environmentally friendly energy increases, development of related parts for electric vehicles is rapidly progressing.

한편, 종래의 자동차용 공조장치는 상하 또는 좌우방향 온도차를 제어하기 위해 에어 믹싱 도어를 사용하였다. 즉, 엔진 냉각수로 뜨거워진 열교환기를 통과하는 공기의 양을 조절하여 온도를 제어하였는데 운전석과 조수석의 온도를 조절하기 위해 별도의 온도조절도어와 도어를 구동하기 위한 소형모터를 구비해야 하며, 이에 따라 제작비용이 증가하고, 공조장치 본체의 크기가 증가하는 문제점이 있었다.
On the other hand, the conventional air conditioner for a vehicle used an air mixing door to control the temperature difference in the vertical direction. In other words, the temperature was controlled by adjusting the amount of air passing through the heat exchanger heated by the engine coolant, but to control the temperature of the driver's seat and the passenger seat, a separate motor and a small motor for driving the door should be provided. There was a problem that the manufacturing cost increases, the size of the air conditioning apparatus body increases.

본 발명은 상기의 문제점을 해소하기 위한 이중 PTC 히터를 이용한 차량용 난방장치에 관한 것으로서, 특히 전기자동차의 공조장치에서 기존의 온도조절도어 및 도어구동 모터 없이도 상하방향과 좌우방향에서 발생하는 온도차를 독립적으로 제어하여 사용자에게 맞는 최적의 환경을 제공하기 위한 것을 목적으로 한다.
The present invention relates to a vehicle heating apparatus using a double PTC heater to solve the above problems, in particular, independent of the temperature difference generated in the up and down direction and the left and right direction without the existing temperature control door and door driving motor in the air conditioner of the electric vehicle It aims to provide the best environment for the user by controlling the system.

이러한 본 발명은 차량 내부에 PTC 히터가 이중으로 구비되되; 상기 PTC 히터와 연동되어 풍향, 운전석 및 보조석의 설정온도, PTC 히터의 토출 온도를 각각 입력받는 입력부와; 상기 입력부를 통해 입력된 풍향, 운전석 및 보조석의 설정온도, PTC 히터의 토출 온도를 바탕으로 상기 PTC 히터의 발열부 출력을 각각 제어하는 PWM 제어신호를 검출하여, 상기 PWM 제어신호를 제어하는 제어부와; 상기 제어부로부터 출력된 PWM 제어 신호에 따라 상기 발열부에 전원을 공급하는 전원공급부로 구성함으로써 달성된다.
This invention is provided with a double PTC heater inside the vehicle; An input unit interlocked with the PTC heater to receive wind direction, set temperatures of the driver's seat and auxiliary seat, and discharge temperatures of the PTC heater; A control unit for controlling the PWM control signal by detecting a PWM control signal for controlling the output of the heating unit of the PTC heater based on the wind direction inputted through the input unit, set temperatures of the driver's seat and auxiliary seat, and discharge temperatures of the PTC heater; ; It is achieved by configuring a power supply unit for supplying power to the heating portion in accordance with the PWM control signal output from the control unit.

이상과 같은 본 발명은 전기자동차의 냉각기와 히터를 통과한 바람의 상하방향 또는 좌우방향에 대한 온도차를 독립적으로 제어함으로써 고객의 요구에 대응하는 최적의 환경을 유지할 수 있게 하는 동시에, 별도의 온도조절도어 및 도어조절 모터 없이도 상하좌우 개별 온도조절이 가능하게 하여 상품성을 향상시키는데 효과기 있는 발명인 것이다.
The present invention as described above by independently controlling the temperature difference in the vertical direction or the left and right direction of the wind passing through the cooler and heater of the electric vehicle to maintain the optimum environment corresponding to the customer's needs, and at the same time separate temperature control It is an invention that is effective to improve the merchandise by allowing individual temperature control up, down, left and right without the door and the door control motor.

본 발명의 이중 PTC 히터를 이용한 차량용 난방장치는 도 1 내지 도 5에 도시된 바와 같이, PTC 히터(100)와 연동되는 입력부(101)와 제어부(102)가 구비되며, 상기 제어부(102)로부터 출력된 PWM 제어 신호에 따라 PTC 히터(100)의 발열부(100a)에 전원을 공급하는 전원공급부(103)가 구비되어 상하방향과 좌우방향까지 온도제어가 가능하게 하여 최적의 환경을 유지할 수 있게 하는 것을 그 기술상의 기본 특징으로 한다.
As shown in FIGS. 1 to 5, the vehicle heating apparatus using the dual PTC heater of the present invention includes an input unit 101 and a control unit 102 interlocked with the PTC heater 100, and from the control unit 102. In accordance with the output PWM control signal is provided with a power supply 103 for supplying power to the heat generating portion (100a) of the PTC heater 100 to enable the temperature control up and down and left and right directions to maintain the optimum environment It is said that it is basic technical feature.

이하 본 발명의 이중 PTC 히터를 이용한 차량용 난방장치에 대한 각 구성요소를 첨부한 도면을 참조하여 하나씩 살펴보면 다음과 같다.Hereinafter, referring to the accompanying drawings, each component of the vehicle heating apparatus using the double PTC heater of the present invention will be described as follows.

본 발명은 도 1 및 도 2에 도시된 바와 같이, 발열부(100a)가 다수 구비되어, 상기 발열부(100a)의 결합에 의해 발열 기능이 가능하게 하는 PTC 히터(100)가 전기자동차의 공조장치에 형성되는 것을 기본으로 한다.1 and 2, the PTC heater 100 is provided with a plurality of heat generating unit (100a), enabling the heat generating function by the combination of the heat generating unit (100a) air conditioning of the electric vehicle It is based on what is formed in the device.

도 1 및 도 2에 도시된 바와 같이, 차량 내부에 PTC 히터(100)가 구비되며, 입력부(101)는 상기 PTC 히터(100)와 연동되어 풍향, 운전석 및 보조석의 설정온도, PTC 히터(100)의 토출 온도를 각각 입력받게 된다.As shown in FIG. 1 and FIG. 2, the PTC heater 100 is provided inside the vehicle, and the input unit 101 is interlocked with the PTC heater 100 to set the wind direction, the set temperature of the driver's seat and the auxiliary seat, and the PTC heater 100. Each of the discharge temperatures of) is input.

제어부(102)는 상기 입력부(101)를 통해 입력된 풍향, 운전석 및 보조석의 설정온도, PTC 히터(100)의 토출 온도를 바탕으로 상기 PTC 히터(100)의 발열부(100a) 출력을 각각 제어하는 PWM 제어신호를 검출하여, 상기 PWM 제어신호를 제어하게 된다.The control unit 102 controls the output of the heating unit 100a of the PTC heater 100 based on the wind direction input through the input unit 101, the set temperatures of the driver's seat and auxiliary seats, and the discharge temperatures of the PTC heater 100, respectively. The PWM control signal is detected to control the PWM control signal.

전원공급부(103)는 상기 제어부(102)로부터 출력된 PWM 제어 신호에 따라 상기 발열부(100a)에 전원을 공급하게 된다.The power supply 103 supplies power to the heat generator 100a according to the PWM control signal output from the controller 102.

이때, PTC 히터(100)의 발열부(100a)는 발열을 수행하는 발열수단이며, 전원공급부(103)는 상기 발열부(100a)에 전원을 공급하는 전원공급수단으로, 상기 전원공급부(103)로부터 전원을 공급받아 발열부(100a)를 통해 PTC 히터(100)의 발열을 실시할 수 있게 되는 것이다.At this time, the heat generating portion 100a of the PTC heater 100 is a heat generating means for generating heat, and the power supply 103 is a power supply means for supplying power to the heat generating portion 100a, the power supply 103 When the power is supplied from the PTC heater 100 through the heat generating unit (100a) will be able to generate heat.

여기서, 발열부(100a)가 발열하게 되는 것은 (+) 와 (-) 전원 공급이 이루어졌을 경우에만 상기 발열부(100a)가 발열하게 되는 것으로, 주위온도에 따라 발열온도가 변화하게 되는데 주위온도가 높으면 저항이 상승하게 되어 전류와 온도가 낮아지게 되며, 주위온도가 낮으면 저항이 저하되어 전류와 온도가 높아지게 된다.Here, the heat generating unit 100a generates heat only when the (+) and (-) power supply is made, and the heat generating unit 100a generates heat, and the heating temperature changes according to the ambient temperature. The higher the resistance, the higher the current and the lower temperature, and the lower the ambient temperature, the lower the resistance and the higher the current and temperature.

한편, 다수의 발열부(100a)는 도 2에 도시된 바와 같이 상호 결합 또는 조립이 가능하게 하여 작업성을 향상시키는 동시에 발열 기능도 증대시킬 수 있게 된다.On the other hand, the plurality of heat generating unit (100a) as shown in Figure 2 can be mutually coupled or assembled to improve workability and at the same time can also increase the heat generating function.

도 4 및 도 5에 도시된 바와 같이, 상기 PTC 히터(100)는 상하온도차를 발생시키기 위한 제1PTC 히터(110)와, 좌우온도차를 발생시키기 위한 제2PTC 히터(120)가 상기 PTC 히터의 전후방향으로 배열되게 하는 것이 바람직하다.As shown in FIGS. 4 and 5, the PTC heater 100 includes a first PTC heater 110 for generating a vertical temperature difference and a second PTC heater 120 for generating a left and right temperature difference before and after the PTC heater.

이때, 제어부(102)는 운전자의 선택풍향 및 운전석 및 조수석의 설정온도, 그리고 운전석과 조수석 PTC 히터(100) 토출온도를 각각 비교하여 제1PTC 히터(110)와 제2PTC 히터(120)의 발열부(100a)의 출력을 각각 제어하는 PWM 제어신호를 각각 출력한다. At this time, the control unit 102 compares the driver's selection wind direction and the set temperature of the driver's seat and the passenger seat, and the discharge temperature of the driver's seat and the passenger seat PTC heater 100, respectively, and generates heat of the first PTC heater 110 and the second PTC heater 120. Each PWM control signal for controlling the output of 100a is outputted.

또한, 상기 제1PTC 히터(110)는 상하 온도차를 제어하기 위해 PTC 히터(100)의 발열부(100a)를 가로방향으로 배치하고, 상기 제2PTC 히터(120)는 좌우 온도차를 제어하기 위해 PTC 히터(100)의 발열부(100a)를 세로방향으로 배치시킨다.In addition, the first PTC heater 110 arranges the heat generating portion 100a of the PTC heater 100 in the horizontal direction to control the vertical temperature difference, and the second PTC heater 120 is the PTC heater to control the left and right temperature difference. The heat generating portion 100a of the 100 is disposed in the vertical direction.

한편, 상기 제2PTC 후면에는 운전석과 조수석의 PTC 히터(100) 토출온도를 측정하는 온도센서(미도시)가 좌우에 각각 일정한 간격으로 이격되어 설치되도록 하는 것이 바람직하다.On the other hand, the second PTC is preferably such that the temperature sensor (not shown) for measuring the discharge temperature of the PTC heater 100 of the driver's seat and the passenger seat is spaced apart from each other at regular intervals.

여기서, 상기 제1PTC 히터(110)는 상하 온도차를 제어하기 위해서 PTC 히터(100)의 발열부(100a)를 가로방향으로 배치하고 각각의 행에 입력되는 전류치를 제어하여 상하온도차를 발생시킨다. Here, the first PTC heater 110 generates the vertical temperature difference by arranging the heat generating part 100a of the PTC heater 100 in the horizontal direction and controlling the current value input to each row in order to control the vertical temperature difference.

제어부(102)에서 상하온도차가 필요한 풍향, 즉 바람의 방향이 사람의 얼굴과 발로 동시에 토출되는 모드에서는 제1PTC 히터(110)의 상측 행에 있는 열온의 온도가 하측 행에 있는 열온 보다 온도가 낮게 제어되도록 전류치를 PWM 제어한다.In the mode in which the wind direction, i.e., the direction of the wind, which requires the up-down temperature difference is discharged simultaneously to the face and feet of the person, the temperature of the heat temperature in the upper row of the first PTC heater 110 is lower than that in the lower row. PWM control current value to be controlled.

또한, 상기 제2PTC 히터(120)는 좌우 온도차를 제어하기 위해서 PTC 히터(100)의 발열부(100a)를 세로방향으로 배치하고 각각의 열에 입력되는 전류치를 제어하여 좌우온도차를 발생시킨다. In addition, the second PTC heater 120 generates the left and right temperature difference by arranging the heat generating unit 100a of the PTC heater 100 in the vertical direction and controlling the current value input to each column to control the left and right temperature difference.

제어부(102)에서 운전석과 조수석의 온도 및 PTC 히터(100)의 좌우 토출온도를 비교하여 제2PTC 히터(120)의 좌우 열에 있는 PTC 히터(100)의 발열부(100a)에 출력되는 전류치를 PWM 제어하게 된다.The control unit 102 compares the temperature of the driver's seat and the passenger seat and the left and right discharge temperatures of the PTC heater 100 to PWM the current value output to the heat generating unit 100a of the PTC heater 100 in the left and right rows of the second PTC heater 120. Control.

한편, PTC 히터의 배열을 역으로 하여 좌우온도차를 발생시키기 위한 제1PTC 히터와, 상하온도차를 발생시키기 위한 제2PTC 히터가 상기 PTC 히터의 전후방향으로 구비될 수도 있게 한다.On the other hand, the first PTC heater for generating the left and right temperature difference and the second PTC heater for generating the vertical temperature difference may be provided in the front-rear direction of the PTC heater by inverting the arrangement of the PTC heater.
